Method Detail

getCurrentValue

public static Object getCurrentValue(DFResultSet.VertexState vs,
                                     DFField f)

Calls getCurrentValue(DFResultSet.VertexState, DFField, boolean) with false for useSubSelection parameter.

getCurrentValue

public static Object getCurrentValue(DFResultSet.VertexState vs,
                                     DFField f,
                                     boolean useSubSelection)

Gets a displayable value for a field matching to a vertex state.

Parameters:

vs - vertex state

f - queried field

useSubSelection - whether to use given selection or its subselection

Returns:

Field value or one of SpecialWidgetValue constants.

getCurrentValues

public static Map<String,Object> getCurrentValues(DFResultSet.VertexState vs,
                                                  List<DFField> fields)

Gets value of currently selected row in vertex state.

Parameters:

vs - vertex state

Returns:

Map of Fields' ids and values OR empty map (in the case of vs==null, or selection is empty) returns

storeValue

public static boolean storeValue(DFField field,
                                 Object newValue,
                                 DFResultSet.VertexState vertexState,
                                 SelectionDescription selection,
